自定义dialog 加底部弹出动画加回调

step1

public class ChoosePicDialog implements View.OnClickListener {    Activity mActivity;    /**     * 下面都是弹出框选择图片的内容     *     */    private Button btnPictureStorage;    private Button btnTakePhoto;    private Button btnCancel;    private OnChoseListener mOnChoseListener;    public interface OnChoseListener {        void onTakePhoto(); //去拍照        void onPicAlbum(); //去开启图库    }    public ChoosePicDialog(Activity activity,OnChoseListener onChoseListener) {        this.mActivity = activity;        this.mOnChoseListener = onChoseListener;        showDialog();    }    private Dialog mDialog;  //更换头像弹出框    /*弹出框，选择头像*/    private void showDialog() {        View view = View.inflate(mActivity, R.layout.photo_choose_dialog, null);        btnPictureStorage = (Button) view.findViewById(R.id.btn_picture_storage);        btnTakePhoto = (Button) view.findViewById(R.id.btn_take_photo);        btnCancel = (Button) view.findViewById(R.id.btn_cancel);        /**设置点击事件*/        btnPictureStorage.setOnClickListener(this);        btnTakePhoto.setOnClickListener(this);        btnCancel.setOnClickListener(this);        mDialog = new Dialog(mActivity, R.style.transparentFrameWindowStyle);        mDialog.setContentView(view, new ViewGroup.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT,                ViewGroup.LayoutParams.WRAP_CONTENT));        Window window = mDialog.getWindow();        // 设置显示动画        window.setWindowAnimations(R.style.main_menu_animstyle);        WindowManager.LayoutParams wl = window.getAttributes();        wl.x = 0;        wl.y = mActivity.getWindowManager().getDefaultDisplay().getHeight();        // 以下这两句是为了保证按钮可以水平满屏        wl.width = ViewGroup.LayoutParams.MATCH_PARENT;        wl.height = ViewGroup.LayoutParams.WRAP_CONTENT;        // 设置显示位置        mDialog.onWindowAttributesChanged(wl);        // 设置点击外围解散        mDialog.setCanceledOnTouchOutside(true);        mDialog.show();    }    /**     * dialog点击事件，开启 相机，图库，取消     */    @Override    public void onClick(View view) {        switch (view.getId()) {            case R.id.btn_picture_storage://图库                mOnChoseListener.onPicAlbum();                mDialog.dismiss();                break;            case R.id.btn_take_photo: //拍照                mOnChoseListener.onTakePhoto();                mDialog.dismiss();                break;            case R.id.btn_cancel://取消                mDialog.dismiss();                break;        }    }}

step2

<?xml version="1.0" encoding="utf-8"?><LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"              android:layout_width="match_parent"              android:layout_height="match_parent"              android:background="#00000000"              android:gravity="bottom"              android:orientation="vertical"              android:padding="5dip" >    <Button        android:layout_width="match_parent"        android:layout_height="wrap_content"        android:background="@drawable/photo_gallery_selector"        android:paddingBottom="10dip"        android:paddingTop="10dip"        android:id="@+id/btn_picture_storage"        android:text="图库"        android:textSize="16sp" />    <TextView        android:layout_width="match_parent"        android:layout_height="0.5dip"        android:background="#DAD9DB" />    <Button        android:id="@+id/btn_take_photo"        android:layout_width="match_parent"        android:layout_height="wrap_content"        android:background="@drawable/photo_camera_selector"        android:paddingBottom="10dip"        android:paddingTop="10dip"        android:text="拍照"        android:textSize="16sp" />    <Button        android:id="@+id/btn_cancel"        android:layout_width="match_parent"        android:layout_height="wrap_content"        android:layout_marginTop="5dip"        android:background="@drawable/photo_cancel_selector"        android:paddingBottom="10dip"        android:paddingTop="10dip"        android:text="取消"        android:textSize="16sp" /></LinearLayout>

style
transparentFrameWindowStyle

    <!--选择头像动画-->    <style name="transparentFrameWindowStyle" parent="android:style/Theme.Dialog">        <item name="android:windowBackground">@drawable/photo_choose_bg</item>    </style>

main_menu_animstyle

    <style name="main_menu_animstyle">        <item name="android:windowEnterAnimation">@anim/photo_dialog_in_anim</item>        <item name="android:windowExitAnimation">@anim/photo_dialog_out_anim</item>    </style>

两个方向透明动画
photo_dialog_in_anim

<?xml version="1.0" encoding="utf-8"?><set xmlns:android="http://schemas.android.com/apk/res/android" >    <translate        android:duration="500"        android:fromXDelta="0"        android:fromYDelta="1000"        android:toXDelta="0"        android:toYDelta="0" /></set>

photo_dialog_out_anim

<?xml version="1.0" encoding="utf-8"?><set xmlns:android="http://schemas.android.com/apk/res/android" ><translate    android:duration="500"    android:fromXDelta="0"    android:fromYDelta="0"    android:toXDelta="0"    android:toYDelta="1000" /></set>

step3

具体使用

       new ChoosePicDialog(this, new ChoosePicDialog.OnChoseListener() {            @Override            public void onTakePhoto() { //去拍照            }            @Override            public void onPicAlbum() {//去打开相册            }};
